I've run checks on some more gcc revisions. Down to a few revisions.

Last known working svn rev: 130324
First known broken svn rev: 130330

A Qt strict-aliasing bug potentially affecting this has shown up; it's possible
that the problem isn't with gcc after all, but only shows up with the current
versions. Running more tests with a fixed Qt version. (At a first quick look, I
don't see how 130324-130330 could un-hide a strict-aliasing bug though,
especially because the strict-aliasing bug is supposed to occur with 4.2.1 as
well)
